The number of command line arguments is $#.  For example:

	% cat foo.sh
	#!/bin/sh
	echo $#

	% sh foo.sh
	0

	% sh foo.sh hello world
	2

	% sh foo.sh "hello world"
	1

The argv[] equivalent is $@.

	% cat foo2.sh
	#!/bin/sh

	for argument in $@ ;do
		echo $argument
	done

	% sh foo2.sh
	%

	% sh foo2.sh hello world
	hello
	world
	%

	% sh foo2.sh "hello world"
	hello world
	%

For more details about the "special variables" of sh, read the sh(1)
manpage.

	% man 1 sh
